Currently, if a driver would be DT only and does not provide a seperate
i2c_device_id table, then the driver is unusable with method 4. I don't
like to have some drivers being capable of it and some not.

The sysfs method creates a device. Its name is matched against
i2c_device_ids only since it does not have a node pointer for DT to be
matched against.
